Panasonic Z95A vs Dreame S100

Panasonic Z95A showcases class when it comes to HDR performance. In luminance tests, it achieves a level of 1800 nits, which has a real impact on movie watching. Scenes from Life of Pi or Gemini Man look fantastic – the television effortlessly renders details and intensity of bright spots, impressing with its power. In more demanding moments, like the final scene from The Meg, one can see how bright light floods the screen. In such moments, brightness drops, which is typical for organic matrices. Nevertheless, a result around 1000 nits can still be considered excellent, still providing very good image quality. Additionally, the television offers excellent coverage of wide colour palettes – as much as 98.6% for DCI-P3 and 74.5% for BT.2020. Thanks to this, colours are not only vivid but also deeply saturated, allowing for a full appreciation of the richness of details, especially in HDR scenes. Such coverage makes the hues look more realistic, and the HDR effect gains in intensity and accuracy. All this impressive HDR effect is thanks to MLA technology, which enables achieving such high luminance and excellent image detail. Because of this, the Panasonic Z95A offers HDR at a level that truly makes a difference.

The Dreame S100 is a relatively bright television. In movie mode, the brightness we measured reached around 600 nits. This is a really good result, although not the highest when considering the competition at this price point. In fullscreen scenes, it is evident that the television can produce an image that impresses with its brightness. Unfortunately, when more complex scenes appeared on the screen, the local dimming algorithm in this model primarily focused on maintaining the deepest blacks. However, this came at the expense of HDR performance – and in a drastic manner. In such scenes, the brightness of bright elements dropped below 100 nits, which is a frankly tragic result, far from any HDR effect. One can improve this aspect, but not without a "however." It is simply necessary to change the local dimming setting in the television's menu, but then the blacks in such scenes simply become grey. It's a pity that Dreame couldn't better refine the local dimming algorithms, and the S100 is another example that the sheer number of local dimming zones does not always translate to a better image. As a consolation, it is worth adding that the Dreame S100 is advertised as a "QLED" type television, although in reality it uses a PFS LED filter. As a result, the colours are appropriately saturated, and the colour gamut coverage of DCI-P3 we measured exceeded 94%.

The best picture mode on the Panasonic Z95A is undoubtedly the Filmmaker mode. It offers quite a good image reproduction, but it is not free from certain issues that require improvement. Firstly, the white balance, for both 4K and HD content, tends to have a dominance of red and blue hues. This causes a slight pinkish tint to the image, particularly noticeable in bright, white scenes. Such deviations can be seen in the comparative photo below, which illustrates this issue well. The Colour Checker test also confirms these discrepancies, showing slight shifts in the dots towards the mentioned shades.

In terms of gamma brightness characteristics, it performs very well, with only minor problems when brightening small details. A greater challenge is posed by the EOTF curve, which is responsible for controlling brightness in 4K HDR content. Here, there is a slight boost in brightness above the reference value, which sometimes makes the image too bright, especially in more demanding scenes. Although the Filmmaker mode is definitely the best choice on the Z95A, these aspects require refinement to fully utilise the television's potential.

We tested the Dreame S100 in 'movie' mode and we definitely recommend using this setting for watching all types of content. Interestingly, within the deeper settings of the television, we also find a dedicated 'Filmmaker' mode, which is now available from almost every manufacturer. However, in the case of the Dreame S100, we do not recommend using it – it blocks all settings related to the picture and does not allow for any configuration in the menu - even motion smoothing. So, how do the factory colours of the S100 fare? Not too badly, but also not the best. The television itself was quite heavily tinted with blue components, which is clearly visible in our white balance measurements. This made the picture artificially brightened, and the colours had a slight bluish tint. This is confirmed by the Color Checker palette, which showed how the colour samples tend to drift towards blue, generating quite significant colour errors. The picture in HDR mode looked definitely better, where the colour errors were not as prominent, although they still fell far from perfection. Here, the white balance was also shifted too much towards blue, causing considerable errors in colour reproduction.

After calibration, Panasonic Z95A shows its full potential, offering an almost perfect picture. The television provides immense adjustment capabilities, which we have fully utilised. The white balance after calibration is positively perfect, and errors in SDR content at the level of 0.5 place it in an absolutely reference standard. The same is true for 4K HDR content – the screen tint has been completely eliminated, and the white balance is now exemplary.

The colour palette and Colour Checker test confirm the excellence of the calibration. Errors below 2 are a result that will satisfy both professional calibrators and enthusiasts of cinematic picture quality. Significant changes have also occurred in the brightness characteristic – the EOTF curve has been flattened, eliminating previous issues with excessive brightness. And a small gamma error has been reduced.

Before calibration, the picture was decent, but now it's an entirely different league. It's a real feast for the eyes, the quality of which is hard to compare to anything else. Panasonic Z95A, after fine-tuning the settings, becomes a true master of colour reproduction.

The Dreame S100 has proven to be a device very amenable to professional calibration. In its menu, we found a plethora of advanced options that allowed us to effectively correct factory errors. Thanks to advanced white balance correction – both in SDR and HDR content – we completely eliminated the excess blue components. The image immediately became much more natural and pleasant to the eye. After fully tuning the colours, the errors in the Color Checker test dropped below Delta E values of 2-3. For the average viewer, this means that any colour distortions have become nearly impossible to perceive with the naked eye. This is truly a pleasant surprise, as new brands in the television market often encounter significant issues with the correct implementation and functioning of sliders in the calibration menu. Here, everything worked as it should. The only thing we must criticise is the way the television manages its brightness in HDR. Due to the specific nature of the local dimming algorithms, anomalies can be seen on the EOTF curve we measured. Where high highlights should appear, there is a slight boosting of the curve above the reference line. In practice, this causes an unnatural brightening of some of the brightest elements in films or games. Despite this minor flaw, professional calibration brings about a huge, very positive change in this model.

In the case of lower quality materials, the function "Gradation Smoothing" is responsible for smoothing tonal transitions. The best results are achieved with an intermediate setting – although they are not spectacular, the function works correctly and does not introduce unwanted effects into the image. It can be rated as average, but sufficient to improve the quality of tonal transitions.

As for digital processing, or upscaling, the image looks surprisingly good. It is vivid and pleasant to the eye, which makes lower quality content, such as standard television or YouTube, look quite decent. However, minor issues can be noted, such as "jagged" edges, for example, branches in the background. Nevertheless, this does not significantly affect the overall viewing experience, and the television handles these materials in an acceptable manner.

For scaling and digital processing in the Dreame S100, the technology that the manufacturer proudly calls Dreamind™ Pro AI is responsible. However, it must be clearly stated that this is not a proprietary processor, but merely a marketing name for a chip made by MediaTek – more precisely, the MT5889 model. Unfortunately, we are talking about a rather outdated unit, from a time when MediaTek lagged significantly behind the competition in terms of performance. This unfortunately has a direct impact on the image as that is what this chip also deals with. The upscaling in the S100 is quite mediocre, and the processor has a tendency to heavily and artificially sharpen edges (fortunately, this can be somewhat tempered with the sharpness slider in the menu). In the options, we also find the "Contour Smoothing" feature, which theoretically is supposed to improve tonal transitions. In practice, it offers almost no improvement – setting it to any level rarely eliminates visible banding of colours, but it can unnecessarily blur elements of the image that should remain sharp.

A separate issue is the phenomenon of overscan (cropping the edges of the frame), which is noticeable here practically all the time. Although there is an option to set the screen to display the full frame in low-resolution materials, this requires activating the previously mentioned Filmmaker mode. And as you know, this mode completely blocks the adjustment of any other sliders in the picture menu. In our test tables, we marked that the television offers an option to disable overscan, as technically such a function exists in the system – however, in everyday use, when maintaining sensible image settings, you will not be able to take advantage of it.

Panasonic Z95A, thanks to its 144 Hz panel, offers excellent image fluidity. For films, there is an "Intelligent Frame Creation" feature that enhances fluidity and reduces motion blur. The user has two sliders at their disposal: "Motion Blur Reduction" – responsible for clearer and sharper details in rapidly moving scenes. "Film Smoothness" – adds fluidity by creating additional frames between the originals, making motion appear smoother and more natural with a "soap opera" effect.

Thanks to this, viewers can adjust the settings to their own preferences. Films and less dynamic material look smooth and natural, which should satisfy most users.

When it comes to motion fluidity, the Dreame S100 performs really well. It features a panel with a refresh rate of 144 Hz, although in reality, the vast majority of people using it in a traditional way will still be limited to 120 Hz (as this is the maximum supported by today's equipment apart from PCs). Thanks to the high refresh rate, the image in motion remains really sharp, largely thanks to the well-functioning MEMC smoother. In the menu, we find predefined modes that allow the television to efficiently generate artificial frames, which effectively improves the fluidity of dynamic sports scenes, but also eliminates image stuttering in film and series materials recorded at 24 frames.

Panasonic Z95A this year shows that the manufacturer has made a huge leap forward in terms of support for gamers. The television offers virtually everything one could expect from a device in this bracket. Support for ALLM (automatic low latency mode) and VRR (variable refresh rate) ensures smoothness and eliminates tearing in dynamic games. The 144 Hz panel allows for incredible fluidity, and additional support for resolutions other than 4K provides greater flexibility, which is a significant advantage for gamers using various configurations.

A unique and quite specific feature is the "Game Bar." Its ball-shaped interface stands out from the competition and allows for quick adjustments of key settings such as VRR, brightness level, or picture mode, without having to interrupt gameplay.

However, in this class of device, there is a minor disappointment – the Panasonic Z95A offers only two HDMI 2.1 ports, instead of four. This is definitely too few for a premium television, especially at a time when many people own more than one device requiring full HDMI 2.1 support, such as a next-gen console or an advanced computer. In this category, it's hard to accept this limitation, especially given the high aspirations of this model. Nevertheless, the television is an excellent choice for gamers, offering versatility and functionality at the highest level.

The Dreame S100 seems almost like the perfect screen for a gamer. The television is equipped with 2 HDMI 2.1 ports with a bandwidth of 40 Gbps, which means that functions like automatic game mode (ALLM) and variable refresh rate (VRR) ranging from 48 to 144 Hz work seamlessly on consoles. It also features a well-designed gaming panel (Game Bar), allowing users to continuously monitor important parameters—from active picture modes to the number of frames rendered by the console, and even the option to add a crosshair in the middle of the screen. All of this looks great on paper; however, the biggest problem with the S100 is the implementation of HDR mode in games. The television does not have the HGiG format implemented correctly. As a result, an unsuspecting user may incorrectly configure the console when first using the screen. Poor configuration can lead to an image that is too dark or too washed out (as a guideline: we suggest setting the brightness in the Xbox console menu to around 600 nits, and in the PS5 to 12 clicks). The Dolby Vision format also proves problematic, as it often would not activate at all between the XBOX and Dreame S100. And when it was finally managed to be activated, playing was not possible due to a very high input lag often exceeding 100ms. If the manufacturer can improve the HDR issue in games via an update, the S100 will be truly excellent hardware for gamers. For now, however, compromises need to be accepted.
